There’s more to the second-generation Chevelle than just the LS6-equipped variant. Even lower spec cars had decent amounts of horsepower, which is why this is generally viewed as a great muscle car. We want to show you a very specific Chevelle though, one that now has a brand-new lease on life.
It’s a 1970 model year Chevelle, which was when the cars benefited from a more coke bottle-like styling and redesigned interiors. Yes, you had your “lowly” engine options like the standard 155 horsepower six-cylinder or the 200 horsepower 307 ci V8, but then came the 330 hp 402 ci V8 and the 350 hp 396 ci V8 – plus of course, you still had the optional LS6 V8 with its 450 horsepower and 500 lb-ft of torque.

This model year also saw the introduction of the 454 ci (7.4L) V8, which you could only get with the RPO Z15 SS Equipment option. This power unit was rated at 360 horsepower and performed admirably. Not as good as the LS6, but it delivered proper performance.

Now, the car you’re looking at here is singing all the right tunes with those SS 454 badges, despite it being fitted with a 396 ci V8 when it first left the factory. Well, that engine is gone now, replaced by a rebuilt 454 ci V8 with fuel injection, a Weiand intake manifold, a Griffin aluminum radiator, dual electric fans, a finned air cleaner assembly, aluminum valve covers, billet serpentine belt system, and a custom exhaust system with Flowmaster mufflers.

According to the seller, this Chevelle is now putting down 529 horsepower and 555 lb-ft of torque, which means that it will absolutely smoke any LS6-equipped brethren over a quarter mile.

All that power is going to the rear wheels via a Tremec five-speed manual gearbox, installed in place of the factory automatic.

In terms of visuals, this car used to be Cranberry Red, but was repainted prior to its refurbishment back in 2018. Exterior highlights now include the Metallic Quartz hue, a functional cowl-induction hood, the previously mentioned SS 454 badging, dual side mirrors, hood pins, chrome bumpers, and a set of 15-inch wheels with SS center caps and BFGoodrich Radial T/A white-letter tires.

You also get power steering, SPC Performance upper and lower control arms, UMI Performance front and rear stabilizer bars, QA1 adjustable front coilovers, custom brake calipers, drilled and slotted rotors, and braided stainless hoses.

As for the interior, you get front bucket seats and a rear bench that have both been retrimmed in black vinyl, color-coordinated dashboard, headliner, headrests and door panels, sound deadening material, three-point seatbelts, a Vintage Air climate control system, an American Powertrain shifter, branded floor mats, a Retrosound stereo, and Dakota Digital instrumentation.

This is one seriously cool Chevelle, which is why it’s going to set you back a pretty penny if you end up with the winning bid. Better hurry though.
